With upgraded H.265 encoding technology, Dahua Lite series network camera has efficient video encoding capacity, which saves bandwidth
and storage space. This camera adopts the latest starlight technology and displays better color image in the condition of low illumination. It
supports SD card storage, dust-proof function, waterproof function and vandal-proof function, complying with the standards of IP67 and IK10
(Supported by some select models).
Smart H.265+ & Smart H.264+
With advanced scene-adaptive rate control algorithm, Dahua smart encoding technology realizes the higher encoding efficiency than H.265
and H.264, provides high-quality video, and reduces the cost of storage and transmission.
WDR
With advanced Wide Dynamic Range (WDR) technology, Dahua network camera provides clear details in the environment of strong brightness
contrast. The bright and dark area can get clear video even in high brightness environment or with backlight shadow.
Starlight
With advanced image processing technology and optical technology, Dahua Starlight technology can provide clear colorful video in
the environment of low illuminance. It widely applies to various environments of low illuminance.
IVS
With advanced video algorithm, Dahua IVS technology supports intelligent functions, such as tripwire and intrusion.
Cyber Security
Dahua network cameras employ a series of security technologies, including security authentication and authorization, access control
protocols, trusted protection, encrypted transmission and encrypted storage. These technologies improve the camera's defense against
external cyber threats and prevent malicious programs from compromising the device.
Protection (IP67, wide voltage)
IP67: The camera passes a series of strict test on dust and soak. It has dust-proof function, and the enclosure can works normal after soaking
in 1 m deep water for 30 minutes.
Wide voltage: The camera allows ±30% (for some power supplies) input voltage tolerance (wide voltage range), and it is widely applied to outdoor environment with instable voltage.
